—All biographies are suitable for all languages?—Bianca asked, somewhat worried; she was studying upstairs language.

—No, luckily you reminded me of the topic— Said the old witch somewhat nervously— They have to have the color of the cover of the learning book they gave you.

—And if we choose another color, what happens?—Adam asked, looking at the great mountain of infinite color books; there were even some colors that the teacher hadn't shown him.

The receptionist settled into her chair, looked at the two children sternly, and said forcefully:

—The cover of each biography reflects the primary language of the decedent's birth hex. If you pick another color, you will not be able to understand the words of the deceased communicated through the biography.

—Is one biography better than another?—Adam asked, noticing that there were too many mountains of yellow books to go through all the biographies he could select.

—They are random, but there are good and bad biographies—the witch answered, looking at the boys, longing for her youth in their childish gazes—There are people in black robes who left their biographies, but there are also people in white robes.

—But why are their white robes? Weren't they from students?—Bianca asked, afraid to choose those biographies.

—Yes, but not everyone manages to get to receive the black tunic— Said the witch with some sorrow; she didn't want to disappoint the two young men— Everyone is a help, black or white!

—But how did those without black robes write their biographies?—Adam asked.

—When you use your biography you will realize how they work— Said the witch in a mysterious way, while she moved her hands in a strange way in front of the children— Go look for your biographies, the best way to learn something is to discover it for yourself!

The two children each went to a mountain of the indicated color, but before they could go very far, a scream resounded from their backs:

—The important thing is what you achieve, not what they achieved! —The old witch shouted, looking at them with affection.

Adam walked through the mountains of books, he wasn't in a hurry, so he searched and searched for a long time. But the receptionist told the truth: all yellow books were the same. So Adam didn't know which was the best biography and which was a useless biography. It got to the point where the indecision began to affect the boy, he would take a book and then return it, and he continued like that for a long time.

Until Adam found a book exactly like all the others. The boy had simply gotten tired of searching for an invisible treasure and decided to trust this yellow book. He took it, he took it to the receptionist and said:

—I want this biography! Can I take it with me?

—Yes, it is yours for the rest of your life, but take good care of it—the old receptionist said happily; her as she wrote something down in a notebook— There is only one godfather in life. You are never allowed to take another.

Bianca was still searching and Adam didn't want to interrupt her, so he decided to go home, meaning the cave.

The road was smooth and Adam had no surprises until he reached the cave. The cave was somewhat changed to what it used to be a month ago. Adam took advantage of the fact that he had money and placed some furniture to make the cave more welcoming, mainly a bed, he always wanted to have one, and now he could; so he didn't hesitate when he had the choice.

The other important piece of furniture that Adam had placed in the cave was a desk and chair that he used to study. Adam also bought some boxes, so he wouldn't keep everything on the floor.

—Did they give you another yellow book?—The eyeless old man asked, noticing Adam's new book.

—A godfather, do you know anything about them?—Adam asked as he settled down to inspect his book.

—A biography, so they gave it to the students—said the eyeless old man, looking at the yellow book—I know something, but not much, in short, I'm a bookcase and not a librarian.
